The Mauritius olive white-eye is a very rare and localized passerine from the family of white-eyes (Zosteropidae). It is one of two white-eye species endemic to the island of Mauritius, the other being the Mauritius grey white-eye.
Region
Mascarene Islands, western Indian Ocean
Typical Environment
Occurs in remnant tracts of native evergreen upland forest in southwest Mauritius, especially in and around Black River Gorges National Park. Prefers mature forest with dense midstory and a good supply of flowering native trees and shrubs. Frequently forages along forest edges, ravines, and in the canopy where flowers and arthropods are abundant. It avoids heavily degraded or exotic-dominated woodland but may pass through mixed habitat to reach resources.
Altitude Range
300–800 m

This is one of the rarest white-eyes, confined to the upland native forests of Mauritius. It feeds on small insects, spiders, nectar, and some fruit, and plays a role in pollination of native flowering plants. The species is threatened by habitat loss and invasive predators, but targeted conservation management has helped some subpopulations persist. It is a flagship for Mauritius forest restoration programs.
Temperament
active and wary
Flight Pattern
short rapid wingbeats with agile, hopping movements between branches
Social Behavior
Typically seen in pairs during the breeding season and in small family groups or loose parties outside it. Builds a small cup nest suspended in dense foliage, where both parents participate in care. Often joins mixed-species foraging flocks with other small forest birds.
Migratory Pattern
Resident
Song Description
A thin, high-pitched series of tsee-tsee notes interspersed with light trills. Contact calls are soft and sibilant, delivered frequently while foraging.
